Marble Snail and hair algae

Someone has suggested to me that the "Marble Snail", Neritina reclivata does
a pretty nice job on hair algae. Has anyone on this list tried these snails
before? They were seen chomping on hair algae in a bare bottom tank but I
was wondering if anyone had tried them in the planted aquarium. They don't
seem to be chewing on the plants. Do they reproduce like mad or is this a
slowly reproducing snail?
thanks,
Gary Lange
